Patent

CA 2154065

The invention relates to a method of producing a preferably tunnel-shaped sound screen (16, 17) over a traffic route (1) while not impeding the moving traffic, which is achieved by placing a temporary covering (6-8) over part of the traffic route, under which covering the traffic can move, and by producing the actual screen over this temporary and preferably rollable covering in the form of a cover, for example by employing the concrete spraying technique inside an inflatable form (9).

Procédé de construction d'un abri ou écran (16, 17), de préférence en forme de tunnel, sur une voie de circulation (1) sans entraver la circulation des véhicules sur celle-ci. A cette fin, on place un abri temporaire (6-8) sur un tronçon de la voie de circulation de sorte que les véhicules puissent circuler sous cet abri, et on fabrique l'écran final par-dessus cet abri temporaire et de préférence enroulable, par exemple par mise en oeuvre d'une technique de pulvérisation de béton à l'intérieur d'un coffrage gonflable (9).
